"Portrait of William Pitt, 1st Earl of Chatham" by Jean André Rouquet at the Victoria and Albert Museum, London - More commonly known as William Pitt the Elder (to distinguish him from his son William Pitt the Younger), this was the British Secretary of State during the Seven Years War and many victories have been attributed to his policies. This is why, for instance, when the British took Fort Duquesne from the French, they renamed it Fort Pitt - now the city of Pittsburgh, Pennsylvania.

William Pitt, later known as "Pitt the Elder", painted by William Hoare in 1754. This was the year he married Lady Hester Grenville.

Bust of William Pitt, 1st Earl of Chatham, by Joseph Wilton, c1766.

John Pitt, 2nd Earl of Chatham, by George Romney, scanned from 'House of Pitt' by Sir Tresham Lever (1947). This is the portrait on which Jacqui Reiter's excellent drawing is based (http://pinterest.com/pin/41236152808369651). It hangs, or used to hang, at Chevening, formerly the home of William Pitt's biographer Earl Stanhope.

William Pitt the Younger

William Pitt engraved by John Jones, 1789, after the Romney portrait (which explains why he looks so handsome!) He's wearing his Chancellor's robes, and his right hand rests on a paper entitled "Regency Bill", meaning this print was produced on the back of the recently concluded Regency crisis (1788-89). This represents Pitt at the high point of his career. With the French revolution just around the corner, things were never again to be so rosy for him as at this precise moment.

One of the two main characters, William Pitt the Younger (1759-1806). Here portrayed by George Romney in about 1783, when he was 23/4. Incredibly he was probably already a cabinet minister when this portrait was painted.

When William the Conqueror seized control of England in 1066, he ordered the construction of several forts on the Thames to defend London against attack. The most famous was the Tower of London, pictured here in the 1400s.

"Portrait of Captain Sir William-Peer Williams, Bt., of the 16th Light Dragoons" by Allan Ramsay (1759) at the Courtauld Gallery, London - I'm actually really excited to see this, because one of my favourite historical fiction series (the "Jack Absolute" series by C.C. Humphreys) has the protagonist serving in the 16th Light Dragoons during the Seven Years War. I've never seen a portrait of an officer from there before, so now I'm definitely stoked.

Charles Stanhope, Viscount Mahon, later 3rd Earl Stanhope (1753-1816), mezzotint by Thomas Watson after Antoine Daniel Prud'homme, 1775. Mahon married Pitt's sister Hester in 1774, and was the father of Lady Hester Stanhope. He was at first a supporter of Pitt's administration, but later they became estranged both politically and personally.

William Wyndham Grenville, 1st Baron Grenville (1759-1834) by John Hoppner, 1800. Pitt's cousin and close ally, Grenville served as both Home Secretary and Foreign Secretary under him. He became Prime Minister for a short period after Pitt's death.

1783-1784 British Portrait medallion of William Pitt the Younger at the Museum of London, London - From the curators' comments: "William Pitt the Younger became the youngest prime minister ever at the age of 24. He had only entered Parliament in 1781....Pitt remained in office continuously until 1801, a period which saw the French Revolution, the start of the Napoleonic Wars and the Act of Union between Britain and Ireland."

John Kitts Birth: May 7, 1762 Death: Sep. 18, 1870 He was born at Bloody Run, in Bedford County, Pa., in 1762, and is, therefore, now in the one hundred and fifth year of his age! In 1776, when fourteen years of age, he was a member of the First Pennsylvania Regiment of the Revolutionary War. He was in the battle of Yorktown, and occupied at one time the position of errand boy or messenger to Washington and Lafayette.
